will any other k series motors throttle body fit ours? because i think thats the next thing i need to get to open up the k20z3

 

Well, if you can get past the DBW throttle system, yeah, it would work.

You would have to change ECU's, fab a custom cable, and get a non DBW pedal.

 

oh i didnt even think about that. wow im dumb

 

Youd also loose your cruise control as well.

The electric TB on the z3 is pretty smooth from what Ive seen. Nice response too.

It could benifit from a little porting out though, if its got enough meat on it to spare. But thats an after warranty thing though.
